Question

Abdul and Ramesh can do a piece of work in 10 and
15 days respectively. They work together for 2 days
and then Ramesh leaves. How long would Abdul
take to finish the remaining work? Please tell me answer fast please ​

Answer 1

Answer:

6 and2/3

Step-by-step explanation:

Abdul does (1/10)th of the work in a day.

Ramesh does (1/15)th of the work in a day.

In 2 days, Abdul and Ramesh do (2/10)+(2/15) = (6/30) +(4/30) = (10/30) or (1/3)rd of the work in a day.

After 2 days the work remaining is (2/3)rd, which Abdul will do in (2/3)/(1/10) = (20/3) or 6 and 2/3rd of the 7th day.
